LED is a light-emitting crystal produced by a superconducting ultra-high intensity lighting, unlike incandescent lamps need to first convert electrical energy into heat energy, thermal energy conversion to light emitting principle. At present, the LED as the emerging next-generation light source, as technology advances, I believe will be of great future development. Then what is led bulbs?
The advantages of LED
(1) long life
LED lamp life of up to 100,000 hours, much higher than incandescent lamps for more than a thousand hours. If we use every day for four hours, then over 60 years of use under normal circumstances, basically more than human life.

(2) energy saving and reduce the cost
LED General 12V-24V DC. Low voltage high optical performance than traditional incandescent lamps to save more than about 80% of the electricity. High-brightness monochromatic LED compared with the traditional light bulb is more expensive, but just the energy-saving advantages will be able to make up for the shortcomings of the high price. If an LED light to be required for a specific brightness power consumption is 15W, then the traditional light bulb to achieve the same brightness, power consumption may be as high as up to 150W.

3 conducive to environmental protection
LED and incandescent lamps, fluorescent lights, luminous works differently, so do not waste too much heat, does not produce toxic gases, difficult to damage, is recognized worldwide as a new generation of environmentally friendly high-tech products.

4 good environmental adaptability
LED as long as the temperature is -40 ° C to -85 ° C, humidity ≤ 65% can normally safe to use. Suitable for use in harsh environments.

5 wide range of applications:
LED light source can be applied in the architectural landscape decoration, highways, bridges, advertising three-dimensional characters, commercial space, airports, subway, hospitals, hotels, cars, computers, mobile phones and other occasions, a wide range of applications.

weak point of LED (what is led bulbs)
1. CRI is poor
LED average CRI in the past to lower the color is not displayed in the LED irradiation incandescent real and likely to cause visual errors and errors of judgment, from the spectral distribution up analysis, a technical problem. But come in phosphors, LED materials used technology to enhance the CRI has been manufacturers gradually pushed up to 90 levels.

2 single LED low power
Low power single LED, the LED light source brightness value is not very high, in order to increase the brightness on the number of LED used in parallel, such as car taillights. Although the single LED is not expensive, but the number is more cost will be high. A single high-brightness high-power LED prices are very expensive and a high-brightness LED also about 5000 candle brightness.

(3) short distance
Although the multi-LED method can improve the brightness of the light source, but did not increase the illumination distance. Because the divergence of the LED light, even if the condenser adjustment, the light from the under the technical standards in the past was only a few dozen meters, LED light source suitable for close lighting is not suitable for long-distance probe according to sexual activity . However, with the enhancement of technological power, the LED light distance can also be elongated, short-term point of view, the LED’s larger problem is the average unit price to be lower.

(4) the heat dissipation problem
LED products, another problem is heat, if we can not efficiently dissipate heat will shorten the life of the product. Industry are working to develop more effective heat dissipation coefficient of the material used in the field of LED.
what is led bulbs? We have detailed the advantages and disadvantages of LED light source, but have fundamental, the LED street light as the emerging next-generation light source, its power-saving, long life and other advantages won the support of the Governments, I believe that under the new technological advances in the global LED industry, LED weaknesses can be gradually overcome, the future prospects for the future, a great future development.
